1 Revision history for Perl extension Net::Z3950::ZOOM.
3 1.29 Mon Oct 14 10:41:28 CEST 2013
4 - Debian/RPM packages now built with YAZ 5.
5 - Do not depend on libyaz4-devel in Debian package
6 (only required for building)
7 - Include the useful example program
8 samples/zoom-delete-records which is installed as part of
10 - Fix documentation of connect() method so that it doesn't
11 imply that it can accept options.
13 1.28 Fri Oct 15 13:34:41 BST 2010
14 - In the test-suite, provide a more explicit report when the
15 scan identity test (display term == term) fails.
16 - The displayTerm==term assertion is now case-insensitive, as
17 it ought always to have been: previously, the test-suite
18 relied on a specific implementaton detail of the
19 test-server, which has recently changed causing extraneous
21 - Also in the test-suite for scan, remove the test that all
22 title-terms are in the general-term list, an assumption that
23 should never have been made.
25 1.27 Wed Aug 11 17:13:07 BST 2010
26 - Support for Index Data build procedures, including making
27 Debian/Ubuntu and Red Hat packages from clean tarballs.
28 - No upstream changes -- packaging only.
30 1.26 Tue Jun 8 16:43:29 BST 2010
31 - Tweak the test-suite so that it works correctly on Fedora
32 Core 12 (2.6.31.5-127.fc12.x86_64). For some reason,
33 attempts to connect to a non-existent host can fail with
34 ERROR_TIMEOUT and no addinfo, rather than ERROR_CONNECT and
35 the hostname as addinfo; and the number of terms to request
36 in a scan needs to be explicitly specified in an option.
37 - Add "debclean" target to generated Makefile.
38 - Remove extraneous and misleading old CVS IDs.
40 1.25 Fri Feb 19 15:04:26 GMT 2010
41 - Fix test-suite not to run the "packages" tests against
42 test.indexdata.com, which has gone away, but against
43 z3950.indexdata.com, like the other tests. A new server
44 runs on a different port for these tests.
45 - Rename zdump.pl to zoomdump, and add it to the set of
47 - Switch to git for version control. Not that it should make
48 any difference to the Perl distribution.
49 - Add semicolons to the commented-out sample configuration
50 lines for Windows in Makefile.PL
52 1.24 Tue Jun 17 11:31:08 BST 2008
53 - When Net::Z3950::ZOOM::record_get() fetches an XML record
54 because the requested OPAC record is empty, it now wraps it
55 in an OPAC wrapper, making the difference invisible to
58 1.23 Mon Jun 9 14:53:15 BST 2008
59 - Net::Z3950::ZOOM::record_get() now patches around the
60 problem of naughty servers that refuse to return anything
61 for an OPAC record when there is no non-bibliographic part,
62 by falling back on requesting an XML record in such cases.
64 1.22 Tue May 27 14:00:12 BST 2008
65 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
66 _when_ appropriate, e.g. for "render" not for "database" and
68 - Remove the unused $len reference parameter from record_get()
69 and $record->get(): this is now used in the underlying C
70 layer to make Perl strings of the right length, and is of no
71 value higher up the stack.
72 - Fix a bug in ZOOM::ResultSet::records(): requests including
73 the last record in the set were incorrectly declined.
74 - Better Debian packaging: use "make debian" to create new
75 "debian/output" directory containing .deb package file,
77 - Clear up a few warnings in ZOOM.xs
78 - Minor documentation improvements.
80 1.21 Mon Oct 29 12:07:25 GMT 2007
81 - In the "typemap" file's handling of opaquechar*, use STRLEN
82 type for _unused_len in instead of unsigned: this prevents a
83 (possibly serious) warning on some 64-bit architectures,
84 although applications that do not use the option_binary()
85 methods will be safe with the previous release.
86 - Add explicit "#include <yaz/log.h>" to ZOOM.xs in the hope
87 of preventing undeclared-function warnings that some users
88 have reported but which I have been unable to reproduce.
90 1.20 Fri Sep 21 17:51:55 BST 2007
91 - Add new sample program, samples/zoom/zoomscan.pl
92 - samples/zoom/zoomtst1.pl now accepts arbitrary options at
93 the end of the command-line, so that (for example) you can
94 specify a non-USMARC record syntax.
95 - Add new functions Net::Z3950::ZOOM::diag_srw_str() and
96 ZOOM::diag_srw_str() to map SRW diagnostic codes into
97 human-readable messages.
98 - ZOOM::Exception() constructor uses diag_srw_str() to fill in
99 the error message, if it is undefined, for SRW errors.
100 - The render() method of ZOOM::Exception(), and therefore the
101 overloaded stringifying operator, deals with exceptions that
103 - Corrected the scan parts of the test-suite that use CQL so
104 that they explicitly perform client-side CQL compilation and
105 send the resulting Type-1 query. Previously, these tests
106 were (accidentally) requesting that CQL be sent as-is to the
107 server, but this mistake was being masked by an error in
108 older versions of ZOOM-C that compiled client-side anyway!
110 1.19 Mon Jul 9 14:09:31 BST 2007
111 - Add $conn->exception() method.
112 - Set version number for Net::Z3950 to 0.99 -- less than the
113 1.0 version number that will be used when it successfully
114 emulates the old Net::Z3950 module, but superseding the last
115 release, 0.51, of that module.
116 - Include samples/zoom/zdump.pl in distribution.
117 - Add "irspy" namespace to samples/zoom/zselect
119 1.18 Mon Feb 26 14:57:48 GMT 2007
120 - When a connection is in asynchronous mode, failing
121 operations (search, scan, etc.) no longer throw exceptions.
122 This is because the event-loop in asychronous applications
123 needs to check for errors anyway, in case the server has
124 returned high-level diagnostics such as "unsupported use
125 attribute". So this check within the event-loop is now the
126 only place where error-checking need be done.
127 - Add new public ZOOM::Connection() function, check(), which
128 throws an exception if an error is pending (even if the
129 connection is asynchronous).
130 - New YAZ logging level, "zoom_check", notes when errors are
131 detected and either left unreported (asynchronous
132 connections) or thrown as exception (synchronous).
134 1.17 Thu Feb 22 20:38:45 GMT 2007
135 - Change Net::Z3950::ZOOM::event() to allocate its array of
136 connection pointers dynamically, so there is no longer an
137 arbitrary limit of 100.
138 - New connection-level option "_check_debug" emits messages on
139 standard error when checking a connection find an error that
140 is about to result in throwing an exception. There is no
141 reason for you ever to use this, though -- pretend you don't
144 1.16 Tue Jan 16 11:18:34 GMT 2007
145 - Require version 2.1.41 or better of YAZ, so that Init
146 Response options are available using
147 $conn->option("init_opt_sort") etc.
148 - Include samples/zoom/zhello.pl to exercise these options.
149 - Add ZOOM_connection_peek_event() and $conn->peek_event().
150 - Require YAZ version 2.1.45, which is the first to provide
151 ZOOM_connection_peek_event().
153 1.15 Fri Dec 1 14:17:49 GMT 2006
154 - ZOOM::Error::INIT is renamed to ZOOM::Error::ZINIT, since
155 INIT is a reserved word in Perl. In version 1.14 and
156 earlier, "require ZOOM" would fail, saying "Too late to run
157 INIT block", and "use ZOOM" would result in
158 ZOOM::Error::INIT having a value equal to its name (why?!)
159 rather than, as intended, Net::Z3950::ZOOM::ERROR_INIT.
160 - Belatedly added documentation for $rec->error() and
163 1.14 Tue Nov 28 17:33:07 GMT 2006
164 - Add $record->error() to return non-surrogate diagnostics,
165 and $record->exception() to return the same information
166 wrapped in a ZOOM::Exception object.
167 - Requires YAZ 2.1.40, which provides ZOOM_record_error().
168 - $conn->error_x() now returns the error-code when called in
169 scalar context, rather than the diagnostic set name.
171 1.13 Sat Nov 4 16:47:00 GMT 2006
172 - ZOOM::Connection::create() may now take either a single
173 argument, which is a ZOOM::Options object, or any even
174 number of argument (including zero), which are key => value
175 pairs of options to set.
176 - ZOOM::Connection::new(), having been refactored to use
177 create(), can now also take a ZOOM::Options argument.
178 - Documentation now includes information on specifying SRW,
179 SRU-over-GET and SRU-over-POST connections.
180 - ZOOM::ResultSet::record() throws a diagnostic if asked to
181 retrieve records out of range for the result-set.
182 - All tests against indexdata.com are now explicitly against
183 z3950.indexdata.com, as the identity of the former name has
186 1.12 (NEVER PUBLICLY RELEASED; these changes are included in 1.13)
187 - Include the useful example program samples/zoom/zselect,
188 which is installed as part of "make install".
189 - Add ZOOM_connection_is_idle() and $conn->is_idle().
190 - Require YAZ version 2.1.35, which is the first to provide
191 ZOOM_connection_is_idle().
192 - Fix bug in ZOOM::Connection class code that made the
193 difficult to subclass -- when called as
194 $class->SUPER::new(@_), the constructor blessed the new
195 object into ZOOM::Connection rather than info the subclass.
197 1.11 Thu Aug 31 16:47:53 BST 2006
198 - Require YAZ version 2.1.17, which has important ZOOM-C
200 - Do not use "-Wdeclaration-after-statement" compiler option,
201 since this supported only by GCC (and only recent versions).
203 1.10 Thu Jun 15 16:42:47 BST 2006
204 - No functional changes, but use Adam's modified API to
205 ZOOM_query_ccl2rpn(). This incompatible change means that
206 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
208 1.09 Tue Jun 13 17:44:43 2006
209 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
210 client-side CCL compilation.
211 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
212 compiler functionality as a Query subclass. This allows
213 client-side CCL to be used for both search and scan.
214 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
215 returned by the client-side CCL facilities.
216 - Supply a sample CCL profile file: samples/ccl/default.bib,
217 copied from the same-named file distributed with YAZ.
218 - The test-scripts t/12-query.t and t/22-query.t are extended
219 to also test client-side CCL searching.
220 - The test-scripts t/15-scan.t and t/25-scan.t are extended
221 to also test client-side CCL scanning.
222 - Documentation updated to describe use of CCL.
223 - Add a nice, simple update client: samples/zoom/update.pl
225 1.08 Thu May 11 22:40:41 BST 2006
226 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
227 bugfix: the old reliance on 2.0.11 was merely a typo.
229 1.07 Thu May 11 17:45:37 BST 2006
230 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
231 refuses to build if it's not present. Thanks to "gregor"
232 (an otherwise anonymous CPAN tester) for notifying me of the
233 previously poor reporting of failure when running against an
235 - No changes to functionality or documentation.
237 1.06 Wed Apr 19 21:11:52 BST 2006
238 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
239 the heck GCC allows this by default I will never understand.
240 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
241 on -Wdeclaration-after-statement, which makes mixed
242 statement/declaration illegal.
244 1.05 Wed Apr 12 13:31:27 BST 2006
245 - Implementation of asynchronous events! The Net::Z3950::ZOOM
246 interface provides this through the event, last_event() and
247 event_str() functions. The ZOOM interface provides it
248 through the ZOOM::event() and ZOOM:event_str() functions,
249 and the ZOOM::Connection class's last_event() function.
250 - New sample programs added illustrating both asynchronous
251 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
252 samples/zoom/zoomtst3.pl respectively. Additional sample
253 programs "async.pl" and "trivial-async.pl" for the ZOOM
254 interface only, the latter being a "shortest possible
255 broadcast search application".
256 - Added documentation on writing asynchronous applications.
257 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
258 events on an asynchronous connection.
259 - Fix ZOOM::Connection::new so that options are handled in
260 accordance with the documentation: applied _before_ the
261 connection is forged, so that "async" and similar options
264 1.04 Mon Apr 3 14:56:11 BST 2006
265 - The ZOOM-Perl layer now provides access to the underlying
266 ZOOM-C's character-translation functionality, through new
267 optional arguments to ZOOM::Record's render() and raw()
268 methods, and a new underlying get() method.
270 1.03 Thu Mar 9 12:55:23 GMT 2006
271 - Allow additional key => value pairs as arguments to the
272 ZOOM::Connectoion constructor; these are added as Connection
273 options before the protocol connection is forged.
275 1.02 Thu Mar 9 11:36:55 GMT 2006
276 - Add interface to yaz_version().
277 - Emit big warning at startup time if YAZ version is less than
278 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
279 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
280 - Fix incorrect ZOOM-package URL in documentation.
281 - Fix typo ("createdb" package) in documentation.
282 - The ZOOM::Connection constructor may now be called with only
283 a single argument (host-string) and does not require a
284 dummy port-number argument.
286 1.01 Thu Dec 22 14:13:34 GMT 2005
287 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
288 so that the declarations they begin with are at the start of
289 the block. This avoid mixed code/declarations. (The
290 "correct" solution is to use INIT: clauses in the XS file,
291 but they don't seem to work: the code in them is slapped
292 down right next to the CODE:, so declarations are not
293 acceptable there either.)
294 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
295 uses a query object to indicate the start-term. This opens
296 the way for using CQL queries for scanning once the
297 underlying ZOOM-C code supports this.
298 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
299 method scan() is renamed scan_pqf(), and a new scan() method
300 is introduced which calls the underlying scan1() function.
301 Thus the scan()/scan_pqf() dichotomy is consistent with that
302 between search()/search_pqf().
303 - The tests t/15-scan.t and t/25-scan.t now also test for
304 scanning by CQL query. To support these tests, a new files
305 is added to the distribution, "samples/cql/pqf.properties"
306 - Remove nonsensical clause about CQL sort-specifications from
308 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
309 client-side CQL compilation.
310 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
311 compiler functionality as a Query subclass.
312 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
313 returned by the client-side CQL facilities.
314 - The test-scripts t/12-query.t and t/22-query.t are extended
315 to also test client-side CQL compilation.
316 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
318 - Add new ZOOM::Log class for logging, providing aliases for
319 the functions in the Net::Z3950::ZOOM layer.
320 - Add diagnostic set to rendering of Exception objects.
321 - Documentation added for CQL compilation and logging.
323 1.00 Wed Dec 14 11:18:33 GMT 2005
324 - First distributed version.
326 0.01 Fri Oct 7 16:14:20 2005
327 - original version; created by h2xs 1.23 with options
328 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
329 --omit-constant --skip-exporter --skip-ppport \
330 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
334 To be done in future releases:
335 - Complete, test and document "update.pl"
336 - Create old-style Net::Z3950 compatibility layer.
337 - Fix memory leaks in callback functions for option sets.
338 - Fix limitation that option-set callback functions must be
339 specified as strings containing package-qualified function
